communities of interest. It could give ecommerce
vendors a better picture of their markets and improve
resource access for Grid computing. It all boils

Labs-on-a-chip are usually made of intricate networks
of channels and chambers. A different approach keeps
microfluidic devices simple by using currents to
mix chemicals or even trap individual cells. The
trick is combining a tiny pillar and a low hum.
